Patent JP-H05243585-A (JP)
Title: Semiconductor device
Inventor: OKADA MASAKI
IPC: H01L29/866
Filed: 1992-02-27
Abstract: PURPOSE:To obtain a diode having a low forward voltage drop and a reverse withstand voltage by forming an N-type diffused region having a dose lower than that of an N-type diffused region and higher than that of an N-type substrate between the P-type diffused region and an N-type diffused region. CONSTITUTION:An N-type diffused region 3f in which P<+> ions of dose lower than that of an N-type diffused region 3e and higher than that of an N-type substrate 1 are implanted is formed between the P-type and N-type diffused regions 2e and 3e, and connected to the region 2e. A reverse withstand voltage Vd3 of a diode D3 is formed at an interval similar to that of a conventional diode of the regions 2e and 3e and hence becomes substantially equal to that of the conventional diode. Since the regions 2e, 3e are connected by the region 3f having low dose, its forward resistance is lower than that of the conventional diode, and a gradient of a forward current can be increased.

Abstract: PURPOSE: To easily and precisely segment a plate frame even in the case that the boundary between the plate frame and the background is indistinct. CONSTITUTION: The photographed signal of a vehicle photographed by a photographing part 11 is converted to multilevel digital data corresponding to the density by a signal conversion part 12. This multilevel digital data is not only stored in a first memory 13 but also presented to an operation processing part 15 and is subjected to quadratic differential processing to obtain a quadratic differential picture, thus obtaining a binary picture. Thereafter, connection data consisting of areas of the same level in the binary picture is extracted, and its features are extracted and are compared with vehicle number data preliminarily stored in a second memory 14. Then, character candidates in the plate are extracted. The position and the frame of the number plate are determined based on character candidates in the plate.  A template is matched to the position and the frame of the number plate determined in this manner, and character candidates in the plate are segmented one by one and are compared with vehicle number data to recognize the vehicle number.

Filed: 1985-03-05
Abstract: PURPOSE:To attain the discrimination of a calling subscriber with respect to a talking time at the use of a detour path trunk by informing the selection of a detour to the calling subscriber. CONSTITUTION:The connection of path 1 is made via a switch SW and a detour tone or a message representing it is sent to the calling subscriber TEL from a tone trunk TNT and the calling subscriber TEL can recognize detour connection.

Abstract: PURPOSE:To accomplish winding with suitable hardness and to enable an easily drawable package by transferring paper formed by short fiber oriented in the direction orthogonal to the longitudinal direction from paper mesh to the other sheet material, and then winding same together with the sheet material. CONSTITUTION:A 90 deg. oriented paper 1 orthogonal to the longitudinal direction is transferred in direction of an arrow by a paper mesh 2. In such a condition, the 90 deg. oriented paper 1 is dehydrated by a paper machine and not yet dried, so that the paper still contains moisture. The 90 deg. oriented paper 1 on the paper mesh 2 is covered with a sheet material 4 by a pair of nip rollers 3, and after passing the nip rollers 3, the 90 deg. oriented paper 1 is transferred onto the sheet material 4. Subsequently, the 90 deg. oriented paper on the sheet material is dried by a driving cylinder 5, and then wound up together with the sheet material. As the 90 deg. oriented paper is thus wound up together with the sheet material, both paper and material can be handled in a body, wound up with satisfactory hardness and easily drawn out.

Abstract: PURPOSE:To easily and quickly rewrite data on a storage element by writing a write signal on the storage element based on an instruction signal inputted from a terminal prior to a read or write operation on the storage element. CONSTITUTION:Read data DO is written on the storage element 2 by controlling and correcting by external data X, Y at a control circuit 1.

Inventor: IFUKURO SADAO
IPC: H04B17/40
Filed: 1979-04-11
Abstract: PURPOSE:To enable the fault position searching for the repeater even at the transmission line featuring the DC breaking property, by using the data pattern in which even numbers of ''1'' signal and the ''0'' signal of the same number of the ''1'' signal emerge continuously and alternately for the data pattern of the monitor signal.

On the other hand, the pass bands different from each other are set previously for band pass filter 26 of each repeater, and the monitor signals featuring the disturbed data pattern are transmitted in sequence to the transmission line with the allotment frequency. Thus both the frequency and the level can be known for the answer signal sent back from monitor line 27. In such way, the position can be detected for the faulty repeater.

IPC: G09B29/10
Filed: 1991-03-08
Abstract: PURPOSE:To restrict a search range for a bearing opposite to a destination, and ensure quick data processing in a vehicle travel route search device using a labeling method. CONSTITUTION:An auxiliary memory device 10 stores the positional coordinates of crossings as junction data between points on roads, the number of junction roads, the number of a crossing for a junction road, the distance for a junction and the bearing of a junction road. A data processing unit 16 searches a shortest route between departure and destination points specified by an input device 14. The search is performed, according to the Dijkstra's algorithm, but the unit 16 evaluates a junction distance with a certain weight, on the basis of a difference between the bearings of a junction road and a destination at each crossing. The junction distance of a junction road at the opposite side of the destination is thereby expanded to restrict a search range.
